Ngayinye yawo isiza ukugcina imizimba yethu iphilile ngezindlela ezahlukene. Namuhla sizokhuluma ngelungu elilodwa elikhethekile lalo mndeni, ivithamini B3, noma i-niacin njengoba sonke siyazi. Kalula nje, i-niacin ibalulekile ekuguquleni ukudla esikudlayo kube amandla. Ibaluleke kakhulu futhi ekugcineni uhlelo lwethu lwezinzwa, uhlelo lokugaya ukudla, kanye nesikhumba siphilile.
Iyini ngempela iNiacin?
Ngokuvamile sithola inani le-niacin esilidingayo ekudleni esikudlayo nsuku zonke. Isibonelo, ukudla okufana nenyama ebomvu, inkukhu, inhlanzi, ilayisi elinsundu, amantongomane, imbewu, ubhontshisi kanye nobhanana konke kucebile nge-niacin. Izinkwa eziningi kanye nokusanhlamvu esikuthenga esitolo nakho kune-niacin engeziwe kukho.
Ngezinye izikhathi, odokotela bangase banikeze imithamo ephezulu ye-niacin, ikakhulukazi ukulawula amazinga e-cholesterol, ukulawula ukukhula kwezimo ezithile zenhliziyo, nokuvimbela izimo ezifana nokulahlekelwa yinkumbulo kanye ne-dementia. Kodwa-ke, ucwaningo lwamuva lubonisa ukuthi kungase kube nengozi ethile yokusebenzisa i-niacin eningi kakhulu.
Ingabe i-Niacin ne-Niacinamide ziyinto efanayo?
Yebo, la magama amabili azwakala efana, kodwa awafani. I-Niacinamide ingenye inhlanganisela eyakheka lapho umzimba wakho une-niacin eningi kakhulu. Njengesengezo, i-niacinamide isetshenziswa kakhulu emikhiqizweni evikela futhi yondle isikhumba kanye nokwelapha induna.
Yiziphi izinzuzo zokusebenzisa i-Niacin?
Ekuqaleni kwekhulu lama-20, ososayensi bathola ukuthi ukuntuleka kwe-niacin kwabangela abantu ukuba babe nesifo sesikhumba esibi esibizwa ngokuthi i-pellagra . Ngalesi sitholo, i-pellagra manje isiyisifo esingavamile kakhulu. Ngokuhamba kwesikhathi, abacwaningi bathole ezinye izinzuzo eziningi zezempilo ze-niacin.
Ukulawula amazinga e-cholesterol
Uma isetshenziswa njengokwelashwa kwe-cholesterol, i-niacin iboniswe ukuthi ikhulisa amazinga e-cholesterol enhle ye-HDL futhi yehlisa ama-triglycerides, uhlobo lwamafutha emzimbeni. Iphinde yehlise amazinga e-cholesterol embi ye-LDL ngezinga elithile. Ngezinye izikhathi i-niacin inconywa ngokuhlanganiswa nama -statin (isb., i-atorvastatin, i-simvastatin), asetshenziselwa ukulawula i-cholesterol.
Kodwa khumbula lokhu kahle:Ukuze wehlise i-cholesterol, i-niacin kumele ithathwe ngemithamo ephezulu kakhulu. Ukuthatha imithamo ephezulu kangaka kungabangela ukulimala kwesibindi, ukuphazamiseka kwesisu, kanye nokungabekezelelani ne-glucose. Ngakho-ke, ungalokothi uthenge i-niacin ekhemisi ngokwakho. Njalo xhumana nodokotela wakho futhi uyisebenzise kuphela ngemithamo enqunyiwe uma eyincoma.
Ukushaya kwegazi
Ngenxa yokuthi i-niacin ilungele i-cholesterol, kuye kwaba nocwaningo oluningi mayelana nokuthi ingasiza yini ekwehliseni umfutho wegazi. Ucwaningo lwamuva nje eShayina lubonise ukuthi abantu abasanda kutholakala benomfutho wegazi ophezulu abathathe i-niacin eningi ekudleni kwabo babenomfutho wegazi ophansi.
Sidinga i-niacin engakanani ngosuku?
Wonke umuntu udinga inani elithile le-niacin ngosuku ukuze asebenze kahle. Leli nani liyahlukahluka kuye ngobudala nezinye izici. Esikhathini esiningi, sithola leli nani ekudleni esikudlayo.
| Iqembu lobudala noma umcimbi | Isidingo sansuku zonke ngama-milligram (mg) |
|---|---|
| Izingane (ngobudala) | 2-16 mg |
| Amadoda | 16 mg |
| Abesifazane | 14 mg |
| Omama abakhulelwe | 18 mg |
| Omama abancelisayo | 17 mg |
| Umthamo omkhulu wansuku zonke womuntu omdala | 35 mg |
Uma udokotela wakho encoma i-niacin, kungcono ukuyithatha kanye nokudla ukuze ugweme ukuphatheka kabi kwesisu. Abanye abantu bangase babe nobuso nentamo ekhanyayo lapho beqala ukuthatha i-niacin. Lokhu akuyingozi. Ukuze kuncishiswe lokhu, udokotela wakho angakweluleka ukuthi uthathe i-niacin kanye ne-aspirin futhi ugweme utshwala nokudla okunezinongo.
Kwenzekani uma uthatha i-niacin eningi kakhulu (umthamo oweqile)?
Nakuba i-niacin ibalulekile emzimbeni, noma yini eningi kakhulu ayilungile. Ungathola i-niacin eningi kakhulu ekudleni kodwa ungabi nezinkinga. Kodwa-ke, ukuthatha i-niacin eningi kakhulu ngendlela yezithasiselo ngaphandle kweseluleko sikadokotela kungaba yingozi. Ukuthatha ama-milligram angu-2,000 no-6,000 ngosuku kungabangela imiphumela emibi kakhulu.
Uma ucabanga ukuthi kungenzeka ukuthi uphuze i-niacin eningi kakhulu, qaphela izimpawu ezilandelayo.
| Izimpawu zokudlula ngokweqile kwe-niacin | |
|---|---|
| Ukushaya kwenhliziyo | Isicanucanu nokuhlanza |
| Ukubomvu okukhulu kwesikhumba kanye nokulunywa | Ubuhlungu besisu nokuqunjelwa |
| Ukuluma nokuxebuka kwesikhumba | Izimpawu ze-gout ziyavela |
Uma unesinye noma ngaphezulu salezi zimpawu, funa iseluleko sezokwelapha ngokushesha. Uma kudingeka, iya eMnyangweni Wezimo Eziphuthumayo (ETU) wesibhedlela esiseduze.
Yikuphi ukudla okune-niacin eningi?
Nazi ezinye zokudla okucebile nge-niacin ezingangezwa kalula ekudleni kwethu okuvamile:
- Ngaphezu kwalokho, izinkwa kanye nokusanhlamvu okuqiniswe nge-niacin
- Inyama ebomvu: inyama yenkomo, isibindi senkomo, ingulube
- Inyama yenkukhu
- Inhlanzi
- Ibhanana
- Ilayisi le-bran
- Imifino (njenge-peas, i-lentile, ubhontshisi oluhlaza)
- Amantongomane (njengamantongomane, ama-cashew)
- Imbewu (njengembewu yethanga, imbewu yelanga)
Imiphumela emibi kanye nezingozi ze-niacin
Ukuthatha imithamo ephezulu ye-niacin kungabangela imiphumela emibi kanye nezingozi ezithile.
Ukuhlanza isikhumba
Lona umphumela ovame kakhulu. Ikakhulukazi uma uqala ukuthatha i-niacin, ubuso bakho nentamo yakho kungase kube bomvu futhi kushise. Kodwa lokhu kuzophela ngemva kwezinsuku ezimbalwa.
Izinkinga Zesisu
Ukuphazamiseka kwesisu, ukuqunjelwa, kanye nohudo kungase kwenzeke. Lokhu kuzoncipha futhi ngokuhamba kwesikhathi.
Ezinye izingozi zempilo
Kunezingozi ezithile ezihlobene nokuphuza imithamo ephezulu ye-niacin. Ingabangela ukulimala kwesibindi, izilonda zesisu, izinguquko emazingeni kashukela egazini, ukulimala kwemisipha, umfutho wegazi ophansi, kanye nezinguquko ekushayweni kwenhliziyo. Ucwaningo olwanyatheliswa ngo-2024 lubonise ukuthi lapho umzimba uphula i-niacin eningi kakhulu, ingabangela ukuvuvukala okulimaza imithambo yegazi futhi kwandise ingozi yesifo senhliziyo.
Ngakho-ke, noma ubani onezinkinga zempilo, njengesifo sesibindi noma sezinso, isifo sikashukela, umfutho wegazi ophakeme, noma isifo senhliziyo , kufanele nakanjani akhulume nodokotela wakhe ngaphambi kokusebenzisa izithasiselo ze-niacin.
Ukusebenzisana okungenzeka neminye imithi
Uma uphuza eminye imithi noma izithasiselo njalo, tshela udokotela wakho ngaphambi kokuqala i-niacin. I-Niacin ingasebenzisana nemithi yesifo sikashukela, imithi yokunciphisa igazi, imithi yomfutho wegazi ophezulu, ama-hormone e-thyroid, kanye namanye ama-antibiotic. Ukuphuza utshwala kwandisa ingozi yokulimala kwesibindi.

- Imithamo ephezulu ye-niacin kufanele ithathwe kuphela ngaphansi kokuqondisa kukadokotela njengokwelashwa kwezimo ezifana ne-cholesterol.
- Ungalokothi uzelaphe ngezithasiselo ze-niacin ezivela ekhemisi ngaphandle kweseluleko sezokwelapha. Lokhu kungaba nezingozi ezinkulu, njengokulimala kwesibindi.
- Ucwaningo lwamuva nje lubonisa ukuthi i-niacin eningi emzimbeni ingandisa ingozi yesifo senhliziyo.
- Uma ukhulelwe, uncelisa, noma unesinye isimo sempilo esingamahlalakhona, kubalulekile ukukhuluma nodokotela wakho ngaphambi kokuthatha noma yiziphi izithasiselo.
